Chester used the regression equation of the weight loss plan to make a prediction within the given data range.

Complete his work to calculate the number of weekly hours of aerobic activity needed for a monthly weight loss of 3

pounds. Round to the nearest hundredth.

1. Regression equation:

7 = 1.1787 + 0 71

2.

3.

Substitute 3 for y:

3 = 1.178x+0.71

Subtract 0.71 from both sides: 2.29 = 1.178x

4. Divide both sides by 1.178:

8:

2.29 1.178

Tize = 1479 x

1.178 - 1.178*

About

hours of weekly aerobic activity will result in 3 pounds of monthly weight loss.
